我们测量了来自新西兰科罗曼德尔半岛泰鲁瓦港和岩石海岸的36种活的海洋软体动物的14C含量。我们确定了适合于放射性碳测年的物种,并表明与开阔的海洋潮下带或河口相比,开阔的海洋潮间带富含14C。我们还通过对距港口5公里的河口双壳贝类Austrovenus Stutchbwyi的分析,发现在台鲁港14C的分布是均匀的。
We measured the 14C content of 36 living marine molluscs from Tairua Harbour and the rocky coast on the Coromandel Peninsula of New Zealand. We identified species suitable for radiocarbon dating and show that the open marine intertidal zone is enriched in 14C compared to the open marine subtidal zone or estuary. We also found a uniform 14C distribution in the Tairua Harbour, by analyzing samples of the estuarine bivalve Austrovenus stutchbwyi collected up to 5 km from the harbor entrance.
